I have just finished a 20cm 47r fin for dezzas new red falcon 49, I haven't used it but I used the plug for the mould yesterday on my naish sp 80 and 5/8 n/p rsr, I was way over finned and a tad over powered with the sail , I was trying to sail off the wind to get to primbee too get the same fin but thinner but was to bugged by the time I got back to head out again
I have 4 versions of this fin, a thick and a thin forward boxed and the same normal boxed , I haven't used the others but arky posted close to a 37knts the last time he sailed with the thinner normal box
theres no weed at primbee this year so there for more chop, so last years 17 & 18 cm fins are on the back burner until the weed comes back
so the ideal fin depth for primbee this year is 20cm+ at 47deg to 45deg , a 20cm fin at 47deg will still get you into some shallow water but much safer in chop
I didn't have any great speeds (32.08 ) mainly because of the power of this fin , the fin has the power of 20 wind turbines and a similar foil ,

hi guys,
i'd rather you hear it from the horses mouth...

C3-fins is going through some major changes right now.
my business partner Dave and me have decided to go our own way.
it will take me a while to figure out where to go from here and i'm looking into several different options at the moment.
the remaining C3-fins stock are being sold off in a sale right now [check the website for details], but the gap to new C3/Boogie designed fins should not be more than a few months.

i'm also going to offer a limited run of true custom fins to fill in the gap. your chance to get anything you ever wanted from C3.
from the teeny tiny speed fin you always wanted with that special rake angle to the weirdo weedo fin for your local pond. just let me know what you are interested in.
i'm open to discuss new concepts or design approaches here in the forum if you like.

cheers
Boogie
